Dynamic Characteristic Analysis of the 3D Spring Model of Column with Triangular Section

Abstract:

In this paper, the equivalent mechanical spring model of the three-dimensional continuum is studied. By using stiffness calculation formulas of three-dimensional continuum column under axial force and bending force, which are primary force states in the column, a mechanical equivalent trusses model with the same width and height is derived. The equivalent model is statically indeterminate trusses system of spring. The 3D spring calculation model can be used in the dynamic characteristic analysis. With the comparison of the first four order frequency values between the solid model and the equivalent spring model, it shows that the equivalent spring model not only have the equivalent stiffness in the static analysis but also have the equivalent dynamic characteristics in the dynamic analysis.
